A friend gave me a box of slitting saws so I decided to make a 1 inch R8 arbor. I should have just made a 3/4" shank arbor instead of R8. I started with an R8 by 1/2x20 store bought arbor and locktited a hunk of steel to the end. Then I had to make an R8 sleeve to hold it in the lathe holding the tolerance to .0005 in. Next I put the arbor in the sleeve with a bolt simulating a drawbar and went to work. Despite my best efforts the stacking of tolerances (I'm not that great anyway) caused about .002 wobble in the blade which was NG. I mounted the whole mess in my chambering fixture and managed to dial in to a few tenths but in truing the 1 inch bore I lost the great fit with the blades that I had originally. Anyhoo I ended up with just a few tenths wobble but now I have .001 runout at the saw teeth. It cuts OK but it has that same yang yang yang sound that I hear on youtube slitting saws. This is what I was trying to avoid. I also have to make an arbor for 1/2" saws but that will have a straight 3/4" shank so I can use my 5c collets in the lathe. The say you learn by your mistakes so how come I'm not a genius by now?
